Cataract surgery is usually performed under local anaesthetic. Your surgeon will make a tiny incision (cut) in your cornea (the outer layer of your eye). Using a tiny probe that emits ultrasound waves, the surgeon will break up the cataract and remove the pieces from your eye. This is called phacoemulsification.
